Alternate universes

Alternate universes are universes of nature similar to our own, with differences that vary from subtle to extreme. The viewer/Futurama's universe does not have an official name, though it was called "Universe A" by the Planet Expresscrew, and "Universe Gamma" by Yivo. "Gamma" implies it is third in a series. Presumably, Yivo considers shkler own "Universe Alpha" with "Universe Beta" heretofore unknown. Parallel universes can be accessed via certain portals, including Parallel Universe Boxes and Anomalies.

The main difference in this Universe is that coin flips have opposite results to those in our own universe, and that color schemes are slightly different here. The Parallel Universe Boxes here are blue, and instead of the sky being blue with clouds, and at night sky being black, the sky is like a rainbow. At night the colors are darker. However, that might be the sky was a flip with blue being one side and random being the other.

Here, none of the inhabitants appear to have eyes, though they are not unfamiliar with the concept of sight. (e.g., when asked if they saw anything, they replied in the negative, rather than question what "see" means) The Parallel Universe Boxes here are white. This universe's Leela would be more normal due to her only difference being eye number, elbow talons, and singing butt boil.

Inhabitants are Bobbleheads who say impolite things and speaking seems to set them in motion. The Parallel Universe Boxes here are pink.

Cowboy Universe

The first alternate universe shown, it was created simultaneously by the Big Bang. In this universe, everybody dresses as cowboys. Before the events of "The Farnsworth Parabox", it was thought the only other existing alternate universe. It is possible that this is the only universe which was extra-dimensionally adjacent to our own, thus limiting access to the others. Through various means, these extradimensional gaps have been bridged.

Pocket Dimension Universe

Where the Infosphere and the Brain Spawn are now. This universe is white with various hues. This implies it may be the reverse of our own, if only chromatically.

Professor Farnsworth built a machine called the what-if machine. This machine, if the user asks it a what-if question, will show an "alternate reality," where the user sees what their life would be like should the question be reality. The known realities shown are listed here.
